There is a Henry and Isabell Muncy living in Wise County in the 1940 census. They had 5 children - Mary, Ernest, Gertrude, Leona and Ada. They were living in McDowell County West Virginia in the 1930 census. I need to figure out Isabell's maiden name. Ancestry.com Trees have her maiden name also as Muncy (Munsey), but I cannot confirm this. I also don't know when Isabell died. As for Henry, there is a Henry E. Munsey living in Mercer, WV in 1920 but I don't know if this is the same person. This Henry went on to remarry in the 1950's to Mary Roberts. Are they same Henry?

Any help is appreciated.
